Complete Moisture & Titration Solutions

Karl Fischer Titrators and Moisture Analyzers are the gold-standard precision instruments that laboratories worldwide rely on for accurate determination of water content in chemicals, pharmaceuticals, petroleum products, foods, polymers, batteries, and a vast range of other materials. Water contamination — even at trace levels measured in parts per million or parts per billion — can damage chemical processes, destroy electronic components, spoil pharmaceutical products, and compromise material performance. Karl Fischer titration, invented by Karl Fischer in 1935 and continuously refined since, remains the most accurate, reliable, and widely accepted method for moisture determination across regulated and research environments alike.

Two principal Karl Fischer techniques cover the full moisture-content spectrum. The Volumetric method (best for higher water contents from approximately 100 ppm to 100%) titrates the sample directly with Karl Fischer reagent until water is fully consumed — fast, robust, and ideal for routine moisture analysis. The Coulometric method (optimal for trace and ultra-trace moisture from approximately 1 ppm down to 0.001 ppm) generates the iodine titrant electrochemically inside the titration cell, delivering exceptional sensitivity for samples with very low water content. Combined with high-precision potentiometric titration for acid-base, redox, complexometric, precipitation, and non-aqueous chemistries, these techniques form the analytical backbone of modern moisture and titration workflows.

Qualitest offers one of the most comprehensive Karl Fischer and titration portfolios available worldwide. The QKF-C30 and QKF-C9 deliver fully automated volumetric KF analysis with 10 ppm sensitivity. 

Measure Moisture. Master Titration.

In every industry where water content matters — and in modern manufacturing, it almost always does — the difference between a successful batch and a costly failure comes down to the accuracy and reliability of your moisture-analysis platform. A wrong KF reading invalidates the QC release, sends defective product to market, fails an FDA audit, or damages an entire production line. The laboratories that consistently deliver world-class moisture data are the ones equipped with Karl Fischer titrators built for sensitivity, repeatability, and full international-standards compliance — and the Qualitest QKF™ and QualiAPT™ portfolios give you exactly that.

Whether you are testing pharmaceutical raw materials, qualifying lithium-ion battery electrolytes, monitoring transformer-oil dielectric quality, supporting fundamental polymer research, or running routine acid-base titrations alongside KF moisture, Qualitest has the analytical platform engineered to meet your exact needs. From the entry-level QKF-C30 to the trace-level QKF-A9 and the versatile QualiAPT™-1000, every Qualitest instrument delivers world-class performance backed by industry-leading service and support.
